An aftermarket part is any part for a car that is not sourced directly from the vehicle’s manufacturer, or OEM (Original Equipment Manufacturer). These parts are certainly less-expensive for the repair of your car and upgrade. Online retailers and independent, local shops may (though not necessarily) offer a selection of aftermarket automotive parts. These automotive parts are made to function similarly to the OEM versions. Aftermarket auto parts, however, have their own pros and cons.
For those with brand-new vehicles, or for vehicles that require a critical part replacement, it is recommended to buy new auto parts to ensure long life and dependable performance. However, if you require a simple part that has a short shelf life, after market parts are a suitable alternative regardless of your vehicles age. Talk to your trusted car mechanic for advice on choosing between OEM parts and after market parts for your vehicle.
You can always bring your own auto parts to a auto dealer. The auto dealer, however, is unable to warranty the purchased part, nor will they be able to guarantee its performance. It is highly recommended to get your vehicle checked by an certified service technician at a local dealership before purchasing any auto parts for installation. The auto-experts will also be able to diagnose the actual problem and recommend an appropriate replacement part, if necessary.
